2. Background Art

Typically, shoulder strap knapsacks, backpacks, or women's bags are widely used in various applications in recent years because of the advantages of light weight and convenient activity.

In spite of the above advantages, however, the shoulder strap bag has the problem that it is inconvenient, to put or withdraw personal belongings into or out of the bag. Further, since the bag is located in the back, it is exposed to the risk of loss.

The shoulder strap bag has small pockets provided on the rear side and lateral sides of the bag to keep personal belongings, such as water bottles and umbrellas, therein. However, it is necessary to put down the bag in order to put or withdraw the belongings into or out of the bag. After being used, the bag must be carried again over the user's shoulder.

Particularly, in the case where a tablet PC, which has recently been spread with great popularity, or valuables, such as a wallet, a watch, or sunglasses, are kept in such pockets, they may be easily damaged. Further, since the bag is located in the back, it has security risks, and there are disadvantages to being a target of crime in congested areas, thereby requiring the user to pay special attention thereto.

BEST MODE

Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a support bag for a knapsack according to an embodiment of the present invention. FIG. 2 is a view illustrating a use state of a support bag for a knapsack according to an embodiment of the present invention, FIG. 3 is a view illustrating another use state of a support bag for a knapsack according to an embodiment of the present invention, and FIG. 4 is a view illustrating still another use state of a support bag for a knapsack according to an embodiment of the present invention.

A support bag for a knapsack according to an embodiment of the present invention includes a bag body 10 having a reception space 11 provided therein and a “

”-shaped zipper member 12 provided on an edge portion thereof to open and close the reception space 11 depending on its moving direction; a first hook 20 provided at a lower end of a rear side of the bag body 10; and a second hook 30 provided at an upper end of the rear side of the bag body 10, and provided in a position biased toward the rear side from a vertical center line out of an upper end of an inner surface facing a user's chest to prevent the support bag from being shaken in left and right directions.

Here, for convenience in use, the bag body 10 is connected to a shoulder strap of the knapsack, and stores therein valuables, such as a tablet PC. The reception space 11 is provided in the bag body 10, and the “”-shaped zipper member 12 is installed thereon to open and close the reception space 11 depending on its moving direction.

In this case, the zipper member 12 is installed to open parts of the upper and front sides of the reception space 11, and is of a two-way type that can be bidirectionally opened and closed. It is preferable that the zipper member 12 includes a waterproof zipper to prevent moisture, such as rainwater, from percolating from the outside to the inside.

Further, the bag body 10 including the zipper member 12 is formed with a size in which a typical tablet PC having a size of 7 to 10 inches can be received, and the thickness of the bag body 10 is in the range of 1 to 5 cm.

In this case, the bag body 10 may be formed to have the thickness of 1 to 5 cm as a whole. However, in order to stably support the tablet PC stored therein, the upper side of the bag body 10 may be formed with a thickness of 1 to 3 cm, and the lower side thereof may be formed with a thickness of 3 to 5 cm.

On the other hand, the first hook 20 is provided at the lower end of the rear side of the bag body 10. The first hook 20 is connected to one side of the lower portion of the shoulder strap of the knapsack to fix the lower side of the bag body 10 to the shoulder strap of the knapsack.

The first hook 20 includes a clip member 22 that can be fastened to the shoulder strap side of the knapsack, and a D-type ring 21 rotatably coupled to the clip member 22 and fixedly connected to the side of the bag body 10.

The reason why the first hook 20 has a dual structure of the clip member 22 and the D-type ring 21 is that when the bag body 10 is connected to the shoulder strap of the knapsack, the load is effectively supported, and thus the bag body 10 is prevented from running idle and being pushed back toward the armpit side.

More specifically, if the first hook 20 is configured only by the shape of the clip member 22, such as a known carabiner, the bag body 10 is unable to be fixed in a free space of the clip member 22, and is pushed back toward the user's armpit side. If the D-type ring 21 is further provided according to the present invention, the push back phenomenon can be blocked by the D-type ring 21 and the clip member 22.

At the upper end of the rear side of the bag body 10 having the first hook 20 as described above, the second hook 30 is provided. The second hook 30 is connected to one side of the upper portion of the shoulder strap of the knapsack to fix the upper side of the bag body 10 to the shoulder strap of the knapsack.

In the same manner as the first hook 20 as described above, the second hook 30 includes a clip member 32 and a D-type ring 31 for the same purpose, and is biased toward the rear side from the vertical center line out of the upper end of the inner surface facing the user's chest to hold the bag body 10 toward the user's chest and to prevent the bag body 10 from being shaken in the left and right directions.

Further, as illustrated in FIG. 3, both ends of a subsidiary shoulder strap 40 are connected to the first hook and the second hook 30 of the bag body 10, and the subsidiary shoulder strap 40 enables the bag body 10 to be independently used in a state where the bag body 10 is not connected to the shoulder strap of the knapsack. That is, the both ends of the subsidiary shoulder strap 40 are fastened to the clip members 22 and 32 of the first hook 20 and the second hook 30, and by carrying the knapsack over the user's shoulder using the subsidiary shoulder strap 40, the bag body 10 can be used in the form of a cross bag.

Hereinafter, the overall use method of the support bag 1 for the knapsack according to the preferred embodiment of the present invention will be described.

First, the zipper member 12 is opened, a tablet PC is put into the reception space 11, and then the zipper is closed.

Thereafter, the clip member 22 of the first hook 20 is connected to the upper portion of the shoulder strap of the knapsack, and the clip member 32 of the second hook 30 is connected to the lower portion of the shoulder strap of the knapsack, so that the bag body 10 is fixed to the shoulder strap of the knapsack.

In this case, since the clip members 22 and 32 are rotatably connected to the D-type rings 21 and 31, the bag body 10 is prevented from running idle and being pushed back toward the armpit side. Further, the second hook 30 is provided in the position biased toward the rear side from the vertical center line out of the upper end of the inner surface facing the user's chest, and thus can prevent the bag body 10 from being shaken in the left and right directions.

While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiment and the drawings. On the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims.

Since various modifications of the present invention can be carried out by those of ordinary skill in the art without departing from the gist of claims, the scope of protection of the present invention is not limited to the above-described specific preferred embodiment.
